Title: Cylinder-piston arrangement for reciprocating engines and reciprocating machines
Inventor: GERNANDT HELMUT
IPC: F16J9/20
Filed: 1981-12-08
Abstract: A cylinder-piston arrangement for reciprocating engines and reciprocating machines, the piston rings and piston ring grooves of which have a profile which widens towards the piston axis, is considerably improved as regards sealing behaviour and wear behaviour and as regards the service life and stabilisation of the piston rings by providing at least one grooved-face type piston ring with a collar extending axially on one side of the actual ring part. This collar is inserted facing away from the pressurisation side of the piston, between two circumferential parts of the piston which are arranged on both sides of the piston ring groove and of which the circumferential part which is nearer the pressurisation side of the piston is designed as a chamber ring with an L-profile groove whereas the second circumferential part has an annular abutment surface for the grooved-face type piston ring, the said face facing in the opposite direction to the pressurisation side of the piston. The sealing and wear behaviour can be further improved by the provision of at least one simple guide ring or pair of guide rings on the piston.

Title: Method and flask system for transferring or transporting fuel elements from a nuclear power station to a storage site
Inventor: VOX ANTON J
IPC: G21F5/008
Filed: 1982-12-03
Abstract: A flask system having three types of flask - an inner flask, a transport flask and a storage flask - is used for the purpose of transferring or transporting fuel elements from a nuclear power station to a storage site. In the pool of the nuclear power station, either the inner flask is firstly put with its cover end open into the transport flask and the fuel elements are then put into the inner flask, or the inner flask which has been charged with the fuel elements remotely from the transport flask is brought into the transport flask. Subsequently, the two flasks are sealed at the cover end and transported as a unit to the storage site. There, the storage flask open at the cover end is prepared, the base of the transport flask is opened, and the latter is lifted together with the inner flask above the storage flask, or set down above the storage flask. The inner flask is then lowered into the storage flask, the transport flask is moved away, and the cover of the storage flask is sealed and the latter is then taken to its site of installation. The base and cover of the inner flask are constructed such that they shield the radioactive radiation so that the transfer of the inner flask from the transport flask into the storage flask is performed without risk.

IPC: B65D41/52
Filed: 1983-09-02
Abstract: A closure cap (1) for drink cans, which have a tear-off opening (5) in their can lid, has a flat cap bottom (8) which is surrounded by a peripheral, approximately cylindrical edge strip (10). The edge strip (10) allows secure, rotatable attachment to a drink can. Provided in the cap bottom (8) is a drinking opening (9) which is slightly smaller than the tear-off opening (5) and which can be moved to be congruent with the tear-off opening (5) by rotating the closure cap (1). To close the drink can, the closure cap (8) is rotated. Mounted at the side of the closure cap (8) is an insertion tab (14) with an insertion slot (15) in which the opening tab (6) of the drink can can be inserted. The closure cap allows opened drink cans to be closed and thus prevents the entry of dirt and insects. The possibility of mounting the tear-off tab (6) on the closure cap (1) reduces the risk of injury by tear-off tabs (6) which are thrown away in a negligent manner. <IMAGE>

Title: Remotely controllable clamping fixture for joining two pipe flanges located in hot cells of nuclear installations
Inventor: MEIER GERHARD
IPC: G21F7/06
Filed: 1983-09-21
Abstract: A remotely controllable clamping fixture for joining to one another two pipe flanges located in hot cells of nuclear installations by means of members which can be braced in the radial direction, over-reach the shape of the flanges by means of an inner profile matched thereto, and, by running onto the inclined surfaces thereof, press the flanges against one another in a sealing fashion, one flange being a so-called fixed flange and the other a so-called loose flange. The clamping fixture need no longer be firmly connected to a pipeline, but is suspended in a lossless fashion on the pipeline firmly mounted in the cell. In the event of defects, the clamping fixture can easily be detached and exchanged by outward transfer. This is achieved by a special construction of the flanges with guide bolts onto which the clamping fixture is firstly mounted, and then the loose flange is pushed from the other side by means of a guide plate onto the guide bolts, whereupon the clamping fixture is moved into its final position and comes to bear by means of a single lock screw. The pipe joint is thus produced in a simple way and can be maintained in the simplest way.
